Runway extension airport Ain Arnat

Three types geosynthetics, originating from the production companies of TenCate Geosynthetics in Linz (Austria), Bezons (France) and Almelo, have been used in extending the runway of the international airport Ain Arnat in Sétif (Algeria). More than 100,000 m² of non-wovens, wovens and geogrids have been used in realizing a sustainable and cost-efficient solution. Furthermore TenCate has offered technical support.

Vertical wall, reinforced soil with geogrid, Sweden

When the postal office should increase their office in Barkarby, Stockholm, it was decided to use geogrids to create a solution which gave them a larger parking area on top of the wall. TenCate made a pre-design of the wall for the designer with given data, height of the wall, soil condition below the foundation, what type of soil to use in the wall and what forces that should be allowed on top of the wall. In the design it was pre-decided to use gabion baskets for facing. TenCate supplied the project with geogrid Miragrid GX 110/30 and Polyfelt TS geotextile and GEOTECHNIK-Bau supplied the gabions. The wall was erected by GEOTECHNIK-Bau.

Lagoon covering, Skutskär outside Gävle, Sweden

Skutskärs Bruk AB dredged in the beginning of the 2000s a new fairway and built a new dock. For accomplishing the project they had to dredge away 600 000 m³ of sediment and moved to a sealed lagoon nearby.

Retaining wall with element of green

Using TenCate geosynthetics, a retaining wall has been erected in the project to widen the railway line between Hamilton and Toronto (Canada). A new robust slope has been constructed using TenCate Miragrid®. Application of this material included an element of green: the full restoration of the habitat of Sunfish Pond, an adjacent pond with rare types of fish.

Wall for sand martins in the Netherlands

The sand martin breeds in colonies in steep banks by lakes, marshes, rivers and sandpits. Flying low over the water, it hunts insects. It generally uses walls that have formed naturally. In several cases, however, human hands have built a sand martin wall because the bird’s natural biotope is increasingly being threatened. For a short time now Woerden (NL) has also had such a wall – thanks in part to the use of TenCate Polyfelt® Rock PEC.

Road under construction in Scotland

In 2008, a consortium of four construction companies rolled up their sleeves to complete the Interlink M74 in Glasgow. This is the missing link between the M74 near Fullarton Road Junction in Carmyle and the M8 just to the west of Kingston Bridge. Large quantities of TenCate Polyfelt Geolon® PET were used. Expected completion: late 2011.

Road through Chott el Hodna (Algeria)

Algeria has seen the completion of a couple of projects that used TenCate geosynthetics. One of these was the construction of a 13-kilometre-long road through Chott el Hodna, a salt lake between Mcif and Ain Khadra. The new road has opened up the salt lake for the inhabitants, who formerly had to make a 75 km detour.

Retaining walls in the Czech Republic

In Kunice and Benešov (Central Bohemia, Czech Republic) TenCate Geosynthetics has been involved in two projects where TenCate Miragrid® GX has been applied. The first concerned the construction of a logistics park, the second the construction of a department store. In both cases reinforced walls (retaining walls) had to be erected, and here our geogrids were the obvious solution.

Retaining wall in Austria

Mountainous (alpine) areas account for more than half of Austria, so motorways and other civil engineering structures in these regions are faced with a substantial number of natural hazards, such as avalanches, ground displacements, mudflows and falling rocks. These can damage, block and undermine roads. Still, retaining walls reinforced with TenCate geosynthetics prove a godsend as a rule when it comes to repairing and preventing the consequences − as two recent projects go to show.

Dam renovation in Rumania

The Teleorman Flood Risk Management project was wrapped up on 28 May 2009, meaning that the renovation of the Botoroaga dam southwest of the Romanian capital of Bucharest is now done and dusted. TenCate Geosynthetics was involved in this undertaking and supplied TenCate Polyfelt® Polymat for erosion control.

TenCate Geotube® technology for dewatering

TenCate Geotube® technology is used to protect coastlines, restore beaches, reclaim land and to store and filter polluted water. TenCate Geotube® is a strong, sustainable method and a cost effective alternative to traditional hydraulic engineering constructions.

Safe waste storage Laogang

The municipality of Shanghai has about 23 million inhabitants. Along with their daily business separate waste impressive off. One of the landfill for waste that lies in Laogang. Partly thanks to the use of TenCate Mirafi ® is safe and durable storage.

TenCate Mirafi® RS580i for a durable subgrade

A short while ago a renewed material became available for reinforcing the subgrade and stabilizing roads: TenCate Mirafi® RS580i. The material integrates the five most important requirements specified in road building.

New lakes in Czech Republic with TenCate geosynthetics

The landscape in the northwest of the Czech Republic is undergoing large-scale revitalization. Where once brown coal was extracted from open-cast mines, recreational facilities are now being built and seven lakes created. TenCate Geosynthetics is involved in their installation, providing geotextile materials and technical support. The realization of Lake Medard at Sokolov is presently in progress.

Geosynthetics for a green appearance

At the end of September, TenCate Geosynthetics North America introduced TenCate Miramesh® SG. This is an open-mesh biaxial geotextile in which synthetic turf fibres have been integrated. It has been designed specifically to be a face wrap material for steepened slope applications and to provide an instant and permanent green appearance. The synthetic turf fibres provide an extra layer of UV protection This innovative produce was developed jointly with TenCate Grass.
